Switching arrangement for the control of the control elements of a dental treatment location

Abstract

A switching arrangement for the control of setting or control elements which are associated with the treatment instruments of a dental treatment location, including a control data memory in which there are stored predetermined control data constants for the treatment instruments. The data is retrievable through a control component for the adjustment of the presently considered control element, and includes a first signal or voltage output arrangement which, through its supplied signals or voltages, facilitates changes in the control data which are conveyed to the control component from the control data memory. A second voltage output arrangement is connected with the control component which supplies a voltage variable from an initial or zero value, and wherein in the active switching thereof, there is prevented the receipt or delivery of signals from the control data memory and of signals or voltages from the first signal or voltage output arrangement through the control component. This renders possible the direct setting of the control elements which are associated with the dental treatment instruments from predetermined initial or zero positions, without necessitating that the signals or data, which have been currently retrieved from the control data memory, be varied in the control component.
